Answer:
5.27 × 10⁷ is the scientific notation for 52,700,000.
<h3>
Answer: 7</h3>
=======================================================
Explanation:
x = number of people
33.25x = cost of the tickets only, without parking
33.25x+14 = add on the cost of parking
33.25x+14 = 246.75
To solve this equation we'll do these two steps in the order mentioned
- Subtract 14 from both sides. This is to undo the +14
- Divide both sides by 33.25 to undo the multiplication.
The idea is we follow PEMDAS in reverse undoing everything so we can isolate x.
So,
33.25x+14 = 246.75
33.25x = 246.75-14 ............. step 1 mentioned earlier
33.25x = 232.75
x = 232.75/(33.25) ................ step 2 mentioned earlier
x = 7 is the final answer
---------------
Check:
7 people go to the amusement park
At $33.25 per person, that amounts to 7*33.25 = 232.75 dollars so far.
Then add the cost of parking to get 232.75+14 = 246.75 to match the total amount spent stated in the instructions. The answer has been confirmed.
Notes:
- This assumes they all went in the same vehicle.
- They'll need to bring more money if they want things like food, drinks, souvenirs, playing carnival games to win prizes, etc.

Answer:
- minimum: 2 at x=0
- maximum: 10 at x=10
Step-by-step explanation:
When looking for extremes, one must consider both the turning points and the ends of the interval. Here, there is a relative minimum at x=7, and a relative maximum at x=3. However, the values at the ends of the interval are more extreme than these.
The absolute minimum on the interval is 2 at x=0.
The absolute maximum on the interval is 10 at x=10.
